Waterproof construction is very huge to the meaning of underground engineering, if water-proofing treatment is improper, basement can leak, when serious
Can not using or calamity occur and caving in for space can be caused, such as subway, culvert, civil air defense constructions and installations can not use, and bring huge
Loss.With the high speed development of capital construction cause, the exploitation of construction waterproofing engineering technology and various waterproof new materials, new process
Also continued to bring out with application.But current waterproof system still has some problems, causes waterproof to fail, it is specific the reason for have：
1st, the waterproof effect of waterproof roll is bad
Show that requirement of the waterproof roll to formation level is high first, if base surface out-of-flatness or peeling, dusting, contained
Water rate is too high, can directly affect coiled material and the bond effect of basic unit, causes coil waterproof layer to produce drum alice phenomenon.Secondly
On showing the cohesive force of waterproof roll and formation level not enough, general waterproof roll only has physics with cast-in-place concrete bottom plate
Mortise and tenon active force, be easy to cause the bonding failure of basal plane and coiled material, produces interlayer string water drainage.It is that market is common anti-again
, as used welded lap, easily there is solder skip, rosin joint, crosses weldering phenomenon there are the insecure problem of edge fit in water coiled material；It is gluing to take
Connect, then adhesion strength is low, easily departs from；Using hot melt overlap joint, heating temperature is not easy control, and adhesion strength is uneven.
